Determination of the temperature-time-relationship during phase transformation, as melting, dissolving and crystallization of one or several components in a mixture takes place by making the mixture flow in a pipeline with a predetermined flow rate and a known temperature. A predetermined amount of heat is added to or removed from the mixture, after which the temperature in a partial amount of the mixture is sensed at a number of measuring points. These are arranged such that the partial amount during the flow through the pipeline is brought to pass these measuring points at time intervals which are determined with use of the flow rate of the mixture. The temperature change in the partial amount is obtained as a function of the time and gives values which are used to determine some or several measuring values for amount, crystal size or size distribution for the component/s in the mixture which have passed phase transformation. |
